Synergetic Visible Light Degradation of Methyl Orange, Rhodamine B and Methylene Blue Over Supra Stoichiometric Ferric and Bismuth Molybdates

P. Suresh [10] | T. Narasimha Murthy | A. V. Prasada Rao


Abstract: Fe2 (MoO4) 3 and Bi2 (MoO4) 3 have been prepared by solution mixing and glycene combustion methods using Bi/Fe nitrate, ammonium heptamolybdate/molybdic acid as precursors. The heat treated precursor powders were characterized in terms of TG, DTA, XRD and FTIR. Phase pure samples were obtained at 400oC with combustion method. Suprastoichiometric samples consisting of excess MoO3 showed enhanced photocatalytic activity for the degradation of Rhodamine B, Methylene blue and Methyl orange dyes in presence of H2O2 under visible light irradiation. Rates of photo degradation observed with Fe/Bi-Molybdate xMoO3 were higher than those obtained for Degusa P25 under the same experimental conditions.
